1.1.0 [2024-09-25]

Features

• Added the default_hostname option to force devices to register using their MAC address instead of their hostname.
• Added support for hotplug events.
• Added error reporting functionality, which sends error logs to the controller if the agent fails to apply a configuration update.
• Implemented a retry mechanism with random backoff for essential operations, including retrieving checksums and downloading configurations from the controller, as well as reporting error statuses.

Changes

Backward incompatible changes

• Renamed /etc/init.d/openwisp_config to /etc/init.d/openwisp-config.

Deprecations

• Deprecated /usr/sbin/openwisp_config in favor of /usr/sbin/openwisp-config to maintain consistency with other files in the package. The path /usr/sbin/openwisp_config is now a symbolic link to /usr/sbin/openwisp-config.
• Deprecated hooks in favor of hotplug events.

Other changes

• Updated logging to capture errors from openwisp-update-config in logd.
• Changed the default bootup_delay to 10 seconds.
• Changed the auto-naming of network.device objects to make it consistent with OpenWISP.

Bugfixes

• Ensured full backup of default UCI files to prevent the loss of configuration.
• Preserved persistent data directories across system upgrades.
• Fixed a registration bug where the agent failed to automatically fall back to the first non-loopback interface when the configured mac_interface was not present.
• Fixed backup process to include all modified files in the backup to ensure no changes are omitted.
• Resolved issues in post-installation and removal scripts in the Makefile, ensuring proper execution during image building.

1.0.1 [2022-06-21]

• Fixed addition of new UCI files which were not previously already present on the file system

1.0.0 [2022-05-10]

Features

• The SIGUSR1 signal can be now used to interrupt the interval sleep
  and check for configuration changes again
• Made the procd respawn parameters configurable
• The agent now stores the any UCI configuration which is overwritten
  by OpenWISP with the goal of restoring it if the piece of
  configuration overwritten by OpenWISP is removed
• Added management_interval and registration_interval options

Changes

Backward incompatible changes

• Remove unneeded SSL package implementation definitions

Other changes

• Made configuration checksum persistent to fix 2 problems:
  1. If the openwisp-config daemon is restarted (e.g. by the
     openwisp-controller via ssh) after it already downloaded the
     latest checksum but before it has applied the configuration, all
     further calls of configuration_changed() (until
     CONFIGURATION_CHECKSUM is deleted, e.g. by a reboot) will imply
     that everything is already up-to-date, although the
     configuration was never applied
  2. prevents the configuration from being downloaded and written
     again after a reboot
• Do not wait for management interface during registration: If
  openwisp-config is not registered yet, do not wait for the
  management interface to be ready because we can assume the
  management interface configuration is not present yet
• Increased report status retries: in some cases the report status
  operation may fail because the network reload could take a few
  minutes to complete (eg: in mesh networks scenarios) and therefore
  the agent must be a bit more patient before giving up
• Refactored init script to make it more consistent with the best
  practices used in the OpenWrt community
• If the agent receives 404 response from the server when downloading
  the configuration checksum, after the number of attempts specified
  in checksum_max_retries fail, the agent assumes the device has
  been deleted from OpenWISP and exits

Bugfixes

• Use configured curl timeout values in default configuration test;
  Without this fix, it's possible that the configuration test fails
  while the regular checksum fetch succeeds
• Ensured config download error is detected: adding the --fail flag
  to curl makes it exit with a non zero exit code in case the server
  respond with an HTTP status code which is not 200 OK, without this
  fix, a bad response is interpreted as a valid configuration and the
  agent removes the old configuration, then installs the new
  configuration, which fails and the router remains with an empty
  configuration, effectively causing a disruption of service
• Fixed post-registration-hook logging line which was mistakenly
  mentioning post-reload-hook instead of post-registration-hook
• Fixed service reload handling for unnamed uci sections: the openwisp
  agent modifies the configuration on first contact by rewriting all
  anonymous UCI sections into na

0.5.0 [2020-12-20]

Features

• Added support for Template Tags
• Send hardware and software information (hardware model, operating system, soc) during registration and boot (too keep it up to date)
• Added post-reload-hook and post-registration-hook
• Added management_interface config option, which allows sending the IP of the management interface to OpenWISP, a pre-requisite for enabling features of OpenWISP as push updates, firmware upgrades and fping health checks
• Added support for hardware ID / serial number
• Added random bootup delay
• Added default_hostname config option
• Improved automatic recovery of previous backups when configuration updates fail
• Added post_reload_delay and test_retries config options

Changes

• Backward incompatible change: list options are now overwritten to prevent duplication
• Improved log message in case of registration failure
• Allow $MAC_ADDRESS to be bridge
• Removed polarssl
• Check sanity of downloaded UCI files before applying them
• Give up with registration only when 403 is returned by the server
• Show entire registration error message in logs
• Updated examples and precompiled packages to use OpenWRT 19.07
• Made check of OpenWISP Controller header case insensitve

Bugfixes

• Ensured order of UCI sections is preserved during config write
  operations, handle special section types
• Ensure anonymous UCI config sections are handled well
• Ensure removal of files only includes items which are not in the new downloaded configuration
• Fixed duplication of list options
• Fixed a bug that caused /etc/config/openwisp to be overwritten
